A harrow is an agricultural tool used to break up and smooth out the soil after it has been plowed. It consists of a frame with sharp, metal teeth or tines that penetrate the ground, helping to eliminate weeds and prepare the seedbed for planting. Harrows can be pulled by tractors or horses, making them versatile for different farming practices. There are various types of harrows, including disc harrows and spring-tooth harrows, each designed for specific soil conditions and farming needs. By improving soil structure and aeration, harrows play a crucial role in enhancing crop growth and overall agricultural productivity.
